EM1001 Basic Programmable Ethernet Board

The EM1001 is Tibbo's most powerful and versatile BASIC-programmable Ethernet board. The EM1001 is a close relative of the EM1000 Ethernet module. Two devices have the same feature set, including the 10/100BaseT Ethernet port, four serial ports, onboard flash disk, EEPROM, and the RTC with optional backup supercapacitor.

Like the EM1000, the EM1001 board can control the GA1000 Wi-Fi add-on, as well as an external LCD, keypad, buzzer, and many other peripheral components.

Unlike the module, the EM1001 is a self-sufficient board: it has a 12V-to-3.3V switching power regulator, RJ45 connector with magnetics, three LEDs, and the MD button. Thus, the EM1001 does not require a host board to plug into. The EM1001 is the host board.

As such, the EM1001 is equally suited to low-volume production devices and hobbyist projects alike.

Specifications:

Based on high-performance purpose-built 88MHz T1000 IC.

10/100BaseT auto-MDIX Ethernet port with RJ45/magnetics.

Four high-speed serial ports (CMOS-level):

None/even/odd/mark/space parity modes;

7/8 bits/character modes;

Full-duplex mode with optional flow control;

Half-duplex mode with direction control;

Encoding and decoding of Wiegand and clock/data streams.

1024KB flash memory for firmware, application, and data.

2KB EEPROM for data storage.

RTC with an optional backup supercapacitor.

Supports external LCD and keypad.

Programmable square-wave output for external buzzer.

Up to 54 general-purpose I/O lines (including 8 interrupt lines).

Three onboard LEDs:

Red and green status LEDs;

Yellow Ethernet status LED.

Two control lines for externally connected LEDs.

Software- and hardware-controlled onboard PLL.

Reliable power-on/brown-out reset circuit.

Powering options:

Through the switching power regulator with 8-20V input range;

Using regulated 3.3V power (the regulator is bypassed).

The regulator can provide up to 1.3A of 3.3V power to external devices.
